Our Testing Process
How every batch reaches you.
A consistent three-stage protocol, applied to every batch we receive — no shortcuts, no exceptions.
01
Sourced from a single manufacturer.
Every compound comes from one trusted source we have a long-standing relationship with. Single-supplier sourcing means a single chain of custody and a single set of standards — no anonymous middlemen, no batch surprises.
02
Independently tested at Janoshik Analytical.
Each batch is submitted to Janoshik Analytical — a laboratory specialising in peptide identity and purity. Both HPLC and mass-spec analysis are performed. We do not pay for favourable results and we do not edit the reports we receive.
03
Published in full, traceable to the lab.
Every certificate carries a unique verification key. Enter it directly on Janoshik.com to confirm authenticity — no need to take our word for it. Reports go up unedited as soon as we receive them.
Verify Independently
Don’t take our word for it.
Every Janoshik report carries a unique verification key in the bottom-right corner. Enter it on Janoshik.com to confirm the report came from them — not us.
